No book number in output file name

[LordKBX]

all is in the title

for myself a made a quick-fix
in wuxiaworld2ebook.py, function button_press()
line 40-41

if name in i[0]:
    raw_info.append(i)

became

if name in i[0]:
     if 'disabled' not in book_number_chosen.state():
        g = list(i)
        g[0] += '-book{}'.format(booknr)
        i = tuple(g)
    raw_info.append(i)

[LordKBX]

also need a modification for the cover image

Thanks for mentioning it!
Will add the functionality in the next commit today or tommorow.

Small note to your fix: E-Reader often get the name out of the dc:title tag, so you might also want to change the input parameter of generate() and line 158 of getify.py
